Carbon steel elbow is a weldable & threaded pipe fitting that allows for change of flow direction, we manufactured them as standard of ASME B16.9 and B16.11. ASTM A234 WPB Elbow is the common used in the oil and gas industires.
We have supplied our buttweld fittings to major customers which business in Oil & Gas, Chemical & Petrochemical, Water treatment, Nuclear & Power Plant, Offshore platform & Shipbuilding. Our products are applicable for any kinds of severe operating condition such as high pressure and high temperature or cryogenic condition.

Fittings that change direction in a piping system are called elbows which available in 90 degree and 45 degree long radius elbow. Both of them has the center line at 1.5 x NPS from elbow end.
Short radius elbow almost same as above long radius, the difference is center line to end is 1 x NPS and available in 90 degree only.
Painting
Firstly, we do the blasting on the body of elbow, to clean the dirt things. Then paint the primer on the inner and outer side. The mainly purpose is against rust during the shipment.
PE Coating
Clean the steel pipe elbow body and wrap the polyethylene tape on it with adhesive. Usually the thickness of coating is 2mm. They are used in the underground pipeline system.
Galvanizing
Take carbon steel buttweld fittings into a bath of molten zinc. That would get more zinc and make the price is high.
We surfaced carbon steel forged fittings with electrogalvanizing because it is pretty and low cost.
